how to cache podcasts with '?' in URL using squid?

[David Wetzel <dave%turbocat.de@localhost>]

Hi,

I want to cache the video files linked in

http://content.zdf.de/podcast/zdf_hjo/hjo.xml

for 24 hours on squid.

I was trying several ways suggested on the web, but it does not seem to work.

maximum_object_size is 150000 KB
I disabled all lines containing a "?"

Any hints? I am using squid-3.1.3 from pkgsrc.

Thanks!

David
